SSL/https-hosting for over the air beta-distribution?

Hello all, I've found a good alternative to TestFlight in the BetaBuilder App for Mac OSX. It creates all the html and manifest-files for testers to download and install my game over the air, only problem is that I need a ssl-secured website to host the files (according to the info I have). I've tried to find somewhere cheap, but they all charge a lot for SSL-options.

Is there anyone who knows a good place to host the files. I don't need my own domain...
